So every time I load the game up it just loads up this tiny screen in the middle. I did download the HD mod, but that doesn't do anything. Even putting it on 1980x1080 it kind of loads up in full screen. But the game itself it still within the same tiny window in the middle. So what's the fix for this?

The main menu has a static resolution, if that's what you mean. It doesn't stretch with higher resolutions.

Yeah nvm. I forgot this can be fixed with my screen settings. Thanks for replying anyway.

Remember too keep the aspect ratio as it is, or the image will be stretched to hell!
